The study of processes occurring at the electrolyte–ferromagnet interfaces under the influence of a magnetic field (phase separation of electrolyte, etc.) are of great interest in the recent years. The magnetic field in this case allows to modify existing or to create new spatiotemporal structures by changing reaction mechanisms. 
In the present work we study the motion of the electrolyte and its structural and temperature inhomogeneities at different configurations of the magnetic field. The rotation of the electrolyte and the distribution of the temperature gradients arising during the reaction were investigated using infrared and visible irradiation. The images of fluid flows for different periods of time are presented in the figure. From left to right: 15 sec., 3 min., and 5 min. 30 sec.
